GENERAL DESCRIPTION
The Ocean Audio 500 Series Master Output module when used in conjunction with
any number of Ocean Audio Input modules, makes a powerful mixing console for the
500 Series rack system.
This two width module provides a master level control for the stereo output together
with accurate bargraph meters that also read the solo levels when activated.
It also provides master level controls and balanced output jacks for the four
auxiliary sends. There is also a solo master level control, headphone level
and output jack plus an independent control room monitor level control.
The module should be carefully slotted into the appropriate two positions of any 500
Series Rack.
By means of the ribbon cable supplied with any Ocean Audio I/P module, connect it to
the I/P module which can be located on either side of the O/P module.
These 16 way connectors can be found on either side of the module printed circuit
board.
The rack can now be powered up.
The following procedures should be carried out without power applied to the
rack.
Now turn the L/R Group Master control until the bargraph displays indicate signal.
It is a good idea to put the L/R Group Master control to approximately three quarters
of it’s travel which will correspond to 0db output. The I/P module level control should
now be advanced to obtain a suitable reading on the bargraph display.
If the ‘SOLO’ master control is turned clockwise and the ‘SOLO’ button on the input is
depressed, the red LED next to the solo master control will flash and the solo signal
will be indicated on the bargraph meters.
By plugging a balanced (stereo) jack into any or all of the four ‘AUX SEND’ jacks the
auxiliary sends can be accessed. Turning the associated master level controlwill adjust
the overall level of the auxiliary send.
